MEAT-BLOCK CLEANER.

Application led August 18, 1926. Serial No. 130,065.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts. to be hereinafter fully described, illus# trated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings whereinv like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a vertical through the device.

Figure 2 is a top plan view, with parts in section.

Figure 3 is an elevation, with parts broken away.

Figure 4 is a view of the brush holder.

Figure 5 is a top plan view of the brush.

Figure 6 is a ldiagrammatic view of the circuit.

In these views, 1 indicates a casing which is formed with the oppositelv arranged extensions 2 at its sides and with the base 3 which has adepending flange 4 which is formed with an `annular internal groove 5. A motor 6 is located in the upper part of the casing and is `provided with the side extensions 7 'which fit in the extensions 2 of the casing. A pair of handles 8 each has its innerv end passing through the extensions 2 and threaded in holes in the extensions 7 so that these handles fasten the motor in vthe casing. A saucer-shaped brush holder 9 engages the groove 5 in the flange 4 and the boss 10 of the said holder is fastened to the motor shaft b v the set screw 11. The

brush head 12 is fastened in the brush holder bv bolts 13 and the said head carries the bristles 14 which are preferably formcdof wire. A split ring 15 encircles the flange 4 and clamps thereto an apron 16 of flexible material,v such as rubberized cloth. A rmg 17 is fastened to the lower edge of the apron sectional view 2 and springs 18 of substantially U-shape have their bights attached to the ring 15 bythe barrels 19 and their extremities fastened to the ring 17, as shown at 20. These springs tend to hold the apron stretched to its fullest extent, but when the device-is placed on the block and a slight pressure applied to the handles, the ring 17 will approach the base so that lapsed, as shown in Figure 1, and thus permit the bristles to engage the block.

The terminals 21 of the motor are connected to a source of supply by the conductors 22 which pass through a tubular extension 23 at the top of the casing, portions of one .of the conductors ofv the handles 8, where they are connected wlth a switch 24 which is so arranged that it can be manipulated by the thumb or finger of the hand of the user which grasps the said handle.

From the foregoing, it will 'be seen that when a block is to be cleaned, it is simply necessary to attach the conductors 22 to a source of supply and then apply pressure on the device through means of the handles 8. This will partially collapse the apron 16 and permit the bristles to contact with the block. The switch 24 is closed to supply current to the motor, which will rotate the brush, as will be understood.

It is thought from the foregoing descrip- .fall within the scope of the appended claims.

1. A cleaning device of the class described comprising a casing having a base portion, a motor held in the upper part of the casing',- abrush holder rotatably` mounted in the base portion, means for connecting the. holder with the shaft-of the motor. a'brushcon'- neeted with the holder, a flexible apron `having its upper portion connected with the base portion and spring means connected with the base portion and the bottom ofthe apron for holding the apron extended.

the apron will be partially coli sj,

passing into one tion' that the advantages and novel features" 2. cleaning device of thev class described I comprising a casing having a base portion',-

a motor in the upper part of the casing, a

brush holder rotatably mounted inthe base portion, means for Yconnecting the holder with the'shaft of the motor, e brush con neoted with the holder, a ex'ible apron hev-y ing its upper portion connected with the base portion, springv means for holding the apron extended, handles passing; through the easing and fastened to the motor for securing the motor yin. the casing and means for supplying current to the motor.

3. A cleaning device of the class described comprising a easing having an enlarged basel portion which is formed vwith e depending ange, an'apron fastened to the flange an ormed-of exible material, a ring on-the lower end of the apron, snbstentiely U- shaped springs having theirbights fastened tothe iange and their extremities fastened to the ring, e motor in the upper part of the casing, handles passing 'through the easing and fastened to portions of the'inotor', e brush' holder rotatably mounted within the space formed by the enge, means for conn nesting the holder tothe motor shaft and holder and having,

a brush fastened to the its bristles extending' into the space formed by the apron.

In testimony Whereo I aiix 'my signature.
